Improving Resiliency of Power Grids during Extreme Events

摘要

This paper presents results of an investigation concerning the resilience of power grids during extreme events such as storms or hurricanes. It considers availability of forecasts which will allow approximate estimation of paths where physical damage to equipment and facilities will be likely. Based on the identified lines which are most likely to be damaged in the next period, an optimal combination of load shedding and line switching actions are determined while taking into account the critical loads that need to be served with highest priority. Simulation results are presented using the IEEE 118-Bus system to illustrate the proposed strategy.
